I temps usually stable but this is the second day in a role I woke up to 10%, Do you think They're still ok? any suggestions to keep it up at night. I sleep for 9 hours and it dropped within that time.

It will help to know what kind of incubator you have. You should have a larger volume of water with a steady surface area. In other words, a deep square bottom container to maintain equal humidity. Otherwise a maxi pad soaked in water works pretty good, but also tends to spike. Drops in humidity won't kill a chick except to stick them at hatch. Average humidity to keep the dehydration of the egg at the right rate. Find something that works and keep the humidity up for a couple of days, then let it even out.

Jen is right on. What she means by square-bottomed container is not that the container has to be a square. Round or rectangular works too. It means the sides of the container need to go straight up and down so the surface area does not change. As she said, the surface area is what counts, not the total volume of water. Wasn't sure that was clear.

I'm not familiar with that model so I'll let others comment specifically. Thanks for including make and model. That really helps.

Your hovabator should have channels in the plastic bottom tray that you fill with water. usually one channel filled is enough for normal incubation. sponges, like maxipads, give you a spike and then they dry out. The shot glass won't work. You can find a container that will hold your sponge and fill it with water so that the top of the sponge sticks out, but this will usually give you way too much humidity. Have you calibrated your hygrometer? Are the plugs in the top?

The hatch I'm on right now hovered at about 16% humidity up until lockdown and they seem to be doing fine. I think you only need to be worried about low humidity after lockdown because that would cause shell stickage. I use paper towels and sponges to boost my humidity to around 70% for lockdown. If you haven't ready it about it before, do a search for dry incubation on the site and read the article, it was very helpful to me
